Getting Started with DB2 Express-C

executable using a command like chmod +x. Afterwards, you can run it in the same
manner as listed above.
5.11 Windows Vista considerations
The User Access Control (UAC) feature in Windows Vista causes applications to start with
standard rights, even if your user ID is a local administrator. This means that any DB2 tool
or command you start in Vista will likely run, but will report problems related to access. To
avoid this problem, use the shortcut called "Command window - Administrator" specifically
created at installation time for Vista users. From this window, you can run other commands
and launch other tools (using the commands shown in Table 5.1 at the beginning of the
chapter). Alternatively, from the Windows Vista Start menu or any DB2 shortcut, find the
desired DB2 tool you want to launch, right-click on it, and choose the Run as administrator
option.
If DB2 extended security is enabled, which is the default (see Chapter 10, Database
Security for details), you must also ensure that your userID is a member of the
DB2ADMNS group in order to launch graphical tools such as the Control Center.
5.12 Summary
In this chapter we looked at the wide array of tools available for administering, configuring,
and managing your DB2 data server.
The arrival in DB2 9.7 of the IBM Data Studio as the main administration tool provides a
new dimension to database administration and development work.
We also discussed a number of now deprecated GUI tools: the Control Center, the SQL
Assist wizard, the Task Center and Journal, and the Health Agent and Monitor. However,
the Command Line Processor and Command Window tools will continue to be a part of the
application in versions after DB2 9.7. Also, the Self Tuning Memory Management tool
remains a big part of the database optimization process.
A key component in the toolbox of any database administrator is the use of scripts to
execute DB2 commands and functions. In this chapter, we took an in-depth look at both
SQL and operating system (shell) scripts, in particular how they are composed, stored and
executed.
Finally, we concluded with a notice about how to ensure that DB2 tools run smoothly on
Windows Vista.
5.13 Exercises
The exercises in this section will let you practice working with scripts in DB2.
Part 1: Populating the EXPRESS database using scripts
In this part, you will populate the EXPRESS database (previously created) using the
Command Editor and two supplied scripts.
